Question

A square is formed by the lines x = a, y=-a and the co-ordinate axes. The length of its
diagonal is​

Answer 1

Step-by-step explanation:

Given lines

x raise to 2

−7x+6=0

(x−6)(x−1)=0

x=6,1

and y raised to 2

−14y+40=0

(y−10)(y−4)=0

y=10,4

SO end points of diagonal be (6,10) and (1,4)

eq of diagonal from 2 points

y−4= 10-4/6-1 (x−1)

y−4= 5/6

(x−1)

5(y−4)=6(x−1)

5y−20=6x−6

6x−5y+14=0
